METALLIC RAILROAD-TIE AN D FASTENER.

Specification of Letters Patent.

Patented July 29, 1919.

Application filed l Tovember 30, 1917. Serial No. 204,700.

To all whom it may concern:

Be it known that LJOHN P. GARDNER, a citizenof the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Meany movement of the rails in relation to the ties and thus eliminate the creeping and spreading of the rails.

Another object of the invention is to provide an improved fastener for. metallic rail road ties embodying a pair of. sliding keys which are mounted in guideways formed on the upper surface of the metallic tie, the keys being adapted to engage the rails and absolutely prevent the same from moving in relation to the ties. r

A still further object of the invention is to provide an improved'plate positioned between the rails and ties to absorb shocks therebetween and an improved means for holding the plate in position on the tie.

A still further object of theinvention is to provide an improved device of the above character, which is use, one that is simple and easy to manufac ture, and one that can be placed upon the market at a reasonable price.

With these and other objects in view, the

. invention consists in the novel construction,

arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part thereof in which:

Figure 1 is a side elevation of the improved railroad tie and fastener and showing the rails positioned on the tie.

Fig. 2 is a plan view of the improved tie showing the rails in locked position thereon.

Fig. 3 is a detail longitudinal section taken on the line 3-3 of Fig. 2.

Fig. 4 is a transverse section taken on the line 4-4 of Fig. 1.

Fig. 5 is a detail perspective view of one 4 of the Lbeam in its original durable and efficient in.

end of the tie showing theguide way for the locking bolts.

Fig. 6 is a detail perspective view of the shock, absorberv plates.

Fig; 7 is a detail perspective View of one of thelocking bolts and showing the bottom of the same. 7

Fig. 8 is a detail plan view of the rails showing the notches in the base thereof for receiving. the locking bolts.

Referring 'to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generally indicates the improved railroad tie, which is of Ibeam' formation and includes the base 2, the upstanding. flange 3, and the upper flange or head 4 which is preferably cut away intermediate its ends as at 5 so as not to interfere with the tamping of the ties. The head 4: of the'tie 1 is preferably cut to provide a plurality of tongues 6 which are bent upwardly to define a guide way 7 the purpose of which will hereinafter more fully appear. The tongues 6 are formed adj acent each end of the tie and on each side of the rail support 8. The rail support 8 is formed by leaving the upper flange or head form. Bolts 9 are slidably mounted in the guide ways 7 on each side of the rails which are indicated by the numeral 10. Certain of the tongues 6 have their upper ends bent angularly and inwardly toward prevent upward movement of thebolt in the guide way and facilitate the positions of the bolts in the guide ways. Positioned intermediate the tongues which have their upper ends bent inwardly as at 11 are looking tongues 12 which continue above the other tongues and are suitably apertured for the reception of a sliding cotter pin or other fastening element 14. Each of the bolts has a transverse semi-circular groove 15 formed in its upper surface, which the cotter pin slides in and absolutely prevents movement of the bolt in relation to the ties. The bolts 9 are formed substantially rectangular and have their inner ends beveled as at 16 which are adapted to engage the flange or base 17 of the rails 10 and prevent upward movement of the same. The lower side edges of the bolts 9 are beveled inwardly toward each other as at 18 to provide a pointed tongue 19 which is adapted to engage in V-shaped each other as at 11 and 7 notches 20 formed in the side edges of the base 17 of the rails and thereby prevent relative movement of; the rails transversely in relation to the ties. The notches can be made in the rails with a chisel or any other suitable instrument. Positioned on the rail supporting flange 8 are shock absorbent pads 21 which are preferably formed of pressed paper or other suitable material andthe same forms a resilient seat for the rails 10 and thus forms a shock absorbing cushion. The side edges of the resilient plate 21 are provided with inwardly projecting lugs 22 which extend toward the tongues 6, the innermost pairs of which are flattened and bent inwardly toward each other as at 23, which prevents upward movement of the plates in relation to the tie. The

lugs 22 are provided with cut out. portions 24 which taper inwardly asat 25 to' receive the V-shaped tongue 19 on the locking bolt 9 and allow the inward movement'of the same.

The grooves 15 which are for'med in the upper surface of the locking bolts 9, are so arranged that the same only aline with the openings 18 formed in the tongues when they are in locked position.

From the foregoing description it will be seen that an improved metallic tie is provided which includes an improved type of rail fastener which will absolutely prevent inward and outward movement of the rails in relation to the ties. 'With ties of this character only three ties are necessary for each rail length, thereby resulting in a great Copies of this patent may be obtained "for five cents each, by

saving of the ties in which a are required for each rail length. 7

In practice, I have found that the form of my invention, illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiments, is the most efficient and practical; yet realiz- Washington, D. G.

greater number ing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor ably mounted between the tongues, certain of said tongues having the upper ends thereof bent inwardly toward each other to form retaining members, certain other of said tongues having alined apertures formed therein, andtran'versely extending locking members slidably mounted in the apertures forengaging said locking bolts to'h'ol'd the same in engagement with the rail.

In combination, a rail having V-shaped notches formed in the side edges of the base 7 thereof, of a rail tie and fastener including a base arranged torec'eive the rail, guideways formed on the base, locking bolts slidably mounted in the guideways, means engaging said bolts to preventtheremoval thereo shock absorbing pads arranged on the base having V -shaped notches formed in the sides thereof, the innerends of said bolts having V-shaped tongues adapted to engage said' notches formed in th'erail and pads, as and for the purpose specified.
